PostgreSQL

What can PostGIS do? What features does it have? What has changed in recent versions? What new features are upcoming in future releases? This talk will cover the history and development of the PostGIS spatial database server.

pgRouting adds routing functionality to PostGIS. This presentation will show the inside and current state of pgRouting development. We will explain the shortest path search in real road networks and how the data structure is important to get better routing results. Furthermore we will show how you can improve the quality of the search with dynamic costs and make the result look closer to the reality. You will learn about difficulties and limitations of implementing routing functionality in GIS applications, the difference between algorithms and their performance.

pgRouting is an extension of PostgreSQL and PostGIS. A predecessor of pgRouting â€“ pgDijkstra, written by Camptocamp, was later extended by Orkney and renamed to pgRouting. The project is now supported by Georepublic and a broad user community.
